Preshopping Plans... Help?

Post by **Maeda** » Tue Feb 25, 2003 4:57 pm

I'm poor so i'm attempting to construct my own kit. I'm looking for 250+ at the wheels with no internals.

Running a 96 SE with 55,000 Miles (Daily Driver)

Current ListUsed FMIC of some sort (suggestions?)370cc InjectorsT3 Turbo (unsure)Exhaust ManiDownpipe of some sortS-AFCPiping (suggestions?)Fuel Pump (suggestions?)

Im thinking to achieve my goals i'll need to run around 10 psi(?)Is the T3 too small for 250+ at the wheels? Should I go for the t3/t04? What kind of boost controller should I be looking for?Maeda:help Add/Change things on the list as you see fit... Help very much appreciated! Thanks in advanced...

you will probably want a larger turbo.

sr 370cc injectors will get you up there, but not 250 at the wheels i don't think.

you can use the walbro pump, 255 liters/hour. cheap and good.

You can use almost any fmic, you just need custom mounts and piping.

do some searching, that's the best way to learn.

might want to look into e-manage instead of afc. if not that then atleast hks afr.

I'm very firmiliar with the search button ^_^

I can't seem to find the specific information though...

Post by **S14Zilvia** » Tue Feb 25, 2003 4:57 pm

There was a very long thread started by matt0941 a while back (month or two) that had some really good responses in it.

There are plenty of threads on turbo selection, "what do I need to get ---hp" and that type of thing.

There's also a lot of good info on other sites from people who have done custom turbo setups.

Btw, I'm assuming you've checked all the faq's you can find.

Post by **signal180sx** » Tue Feb 25, 2003 4:57 pm

Just be sure you researched everything you plan on doing from looking at forums that are plentiful as heck on info. Goodluck!

Post by **Maeda** » Tue Feb 25, 2003 4:57 pm

so nobody can anybody with some KA-T experience answer these questions...?(Thinking the T3/T04 would be a better choice...)

oh and one more... what kind of trim and a/r numbers amd i looking for with the T3/T04?

Post by **ADAMHU** » Tue Feb 25, 2003 4:57 pm

its just that these questions come up so often the experianced people can't stand to answer them anymore...look at some websites and see what every one else is using....then just copy it...

Post by **trpower7** » Tue Feb 25, 2003 4:57 pm

I would recommend at least getting pistons if you are going for those numbers, it would be a real pain to melt one and be screwed.

Post by **noopz** » Tue Feb 25, 2003 4:57 pm

10psi is kinda high for stock internals (pistons, rods) i think ur better off with 7 at the most, Nsport has there stage 1 turbo set to 7psi or somethin like that. They say it provides 240hp at the crank i think. N e way. 10psi is too much, i dont think the clutch would handle it well either. Im fabricating my own turbo, using a 90-96 T28 turbo from a 300zx TT. i got it at a local junkyard for 200bux cad. thats the cheapest way to go. i was told that it was set at 9.5psi stock. as far as other parts, u can get a walbro pump from ebay 4 cheap. and used BOV's n boost controllers from it too. good luck

Post by **96_S14_SE** » Tue Feb 25, 2003 4:57 pm

10psi isnt too much, you just have to know what you are doing. 10psi is too much if you half *** the fuel delivery and other aspects and detonate.

That z32 turbo isnt a t28 btw, sorry to say. From what I know its not even a straight t25 but a t22/t25, hece the term t-to-small. As its only feeding 1.5l of displacement it doesnt need to be big to be stock, unlike the T3 feeding the full 3L of the turbo Z31...

Post by **noopz** » Tue Feb 25, 2003 4:57 pm

Wellllllllll there u go. get your ic and all the neccesary parts. Slap on a z31 turbo, add a nice fuel pump n fmu with some shiny nice injectors, and Slam the pedal till you hit 5000rpm @10psi on stock internals. :thinker

I'm in the same boat with you man.

79k miles on my ka.

I'm going to try to run near 10psi (we'll see if I can work my way up there) using the e-manage and larger injectors and pump. I should be able to push enough fuel to keep from detonating. Tuning is a big concern though.

I just don't want to go SR because I know if I can keep my KA from blowing up I'll be running way more power for way less money and no engine swap.

I bought an intercooler, piping is going to hold me back now. I also have to figure out how to squeeze it in there. A friend and I may try to make a custom manifold, and I'll run a tial external wastegate. Probably a t3/t4 hybrid or just a t3 off a z31.

Good luck, maybe we can help each other out along the way!

I seriously hope you wherent trying to be sarcastic / smart with that post... Thats a very old and dated sohc setup. The fuel delivery is also rather vague. There have been a decent amount of KA'rs running in the 1 bar /15psi range on stock internals. A few on freshalloy have been pushing this for over a year.

I wouldnt go near attempting 10psi on just say 370's and a fmu... You need some type of supplemental system wether it be a s-afc or a jwt retune.. My plan is about 8 - 10 or so. I will use either the z31 t3 or a t3/t4 hybrid, unsure of what style manifold and might make my own if I feel like it, larger injectors (unsure of size yet but 370 min), new w-255 fuel pump, Z32 mafs, jwt retune (when all the details are spec'd) and possibly a s-afc for fine tuning and other reasons.

I am still putting it off untill I can get some seat time in the sts class of soloII. Its basically the reason alot of things havent been done yet that I wanted to do. Once that first mod sends me into SM Ill have to go forward to be semi competitive.

the guy wants a turbo set up. If he's on a budget, i strongly advice not to go too far with the boost. cuz i dun think he would want to rebuild his motor. soo like i said. 10psi is risky, considering that the persons on a budget. thanks for the info on the turbo tho. i guess ur ryte. i posted a question here regarding the 300zx turbo, and got mixed opinions about it. i got a 30day exchange, and hopefully there's a Z31 turbo around.

Post by **Maeda** » Tue Feb 25, 2003 4:57 pm

I Actually ended up with an IHI thats the equivolent of a T3/T04 in terms of specs...

i am now looking for 400cc+ injectors that will drop into the fuel rail...

and im trying to figure out how a 30 inch wide intercooler will fit with a stock bumper...

Still gotta buy/find-InjectorsXS turbo type S BOVGreddy EmanageProfec e-01Revhard manifold (going down there this weekend)Walboro PumpMisc Stuff (oil lines, bungs, etc)Misc Pipes

thanks guys keep the replys comming ^_^

Post by **S14Zilvia** » Tue Feb 25, 2003 4:57 pm

Let me know what you find on the injectors, I'm looking for some as well.

Post by **Syntax360** » Tue Feb 25, 2003 4:57 pm

lol...bet this will be most n00bish question. i'm in this same boat, except I'm not looking for the kind of power u guys are. I'm looking more at 5psi to start. At 5 psi, do I really need to make drastic changes to the fuel system or will it be able to hold it? And do u think i will need an intercooler right away? (keep in mind i live in texas and summer is creeping up.) Also, for just 5psi, the T3 off the Z31 will suffice, right? I really just trying to get my feet wet here and i can't afford the NSport kit.

Post by **d240t2** » Tue Feb 25, 2003 4:57 pm

5psi will be fine with an FMU and no intercooler. I had that setup for a summer living in Houston.

A Z31 T3 would be good up till 9psi...although not optimal. The elbow on the turbine side makes it difficult to fit without some custom work (at least custom manifold and downpipe, obviously).

thanks a lot man. i'm glad to hear it. i'll still probably get an intercooler whenever I can get up money, but i just want to focus on getting some kind of turbo setup...i can always upgrade later. where could I go to get a custom manifold made you think? i see a lot of sites where people make their own out of the stock manifold(?), so how much do ya think it would run me to have someone modify mine? thanks for everything!

Post by **Maeda** » Tue Feb 25, 2003 4:57 pm

same question as above...

who the hells makes a cheaper/better manifold? I'm going down to Revhard this friday but... if i can find it cheaper id rather (a lot of peoples rev hard mani's crack?)

oh and suuposedly 480cc SR20DET injectors will bolt into the fuel rail... and if you find some send um this way ^_^

Post by **Canadian 240SX** » Tue Feb 25, 2003 4:57 pm

Actually the SR ones don't fit, but the CA ones do Just something to keep in mind

No actually sr injectors fit just fine. If you look at the original post he was talking about a 96 dohcCA injectors only fit sohc

anyone have any info on the cost of custom manifold?

Post by **S14Zilvia** » Tue Feb 25, 2003 4:57 pm

Start at around 400. I've seen a few custom mani's.

The executive clean car one is around 600 something.

Ask around.
